English(EN) David vs Goliaths: Singapore builds most accurate clock ever, leaves US and China in dust

新加坡制造出世界上最精确的原子钟，超越美中两国

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-02 08:00

新加坡的研究人员开发出了世界上最精确的原子钟，打破了此前由中国和美国团队创下的纪录。这款利用单个镥离子的新时钟精度极高，在2600亿年的时间里只会慢一秒。这一成就可能导致对秒的重新定义，并代表着计时技术的一项重大进步。 AI

本文如何被排名

Signal score: 0 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; 该集群报道了一个研究团队取得的新科学基准，特别是创造了一个高精度原子钟。[lever_c_demoted from research: ic=1 ai=0.1]
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: other; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: Low; Off-topic or adjacent — cluster remains reachable but doesn't surface in AI-industry rankings.
Story freshness: Same-day; Cluster formed today. Ranking reflects the current source set at time of score.

大卫对抗歌利亚：新加坡制造出有史以来最精准时钟，将美中两国远远甩在身后

A small Singaporean research team has beaten scientists in China and the United States to build the world’s most accurate atomic clock. The clock, built with a single ion of a rare earth metal element known as lutetium, is so precise that it would lose one second every 260 billio…
